SPECIFICATION forming part of Letters Patent No. 543,228, dated July 23, 1895. Application filed April 8, 1895. Serial No. f14,99l. (No model.) I

To all whom it may concern: I Be it known that I, ANDRE 'CHAVANNE, a citizen of the United States, residing at Grass Valley, Nevada county, State of California,

have invented an Improvement in N ozzle- Regulators; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of regulators especially adapted for use in water-nozzles which discharge a stream of water under pressure and in which a slidable plug within the nozzle and in the plane of its axis is adapted who moved back and forth to vary the relation of its point or head with the forward end or tip of the nozzle'in suchla manner as to control the latter between the limits of entirely closing off the water and givingit full and clear exit.

My invention consists in the novel construc tion of the end or head of the plug,.the manner in which it is mounted in the nozzle, and the means by which it is operated, all of which I shall hereinafter fully describe and specificallyclaim.

The object of my invention is to provide a simple and efiective regulator for the nozzles of water-pipes, especially those which are adapted to discharge a stream of" water under high pressure against a water-wheel or other source of power, and by meansiof said regulator to reduce or wholly avoidthe loss of power arising from eddies, windings, or chokings of the stream under high pressure.

Referring to the accompanyingdrawings for a more complete explanation of'my invention, Figure l is a vertical longitudinal section through the nozzle and its water connections, showing my regulator in said nozzle and the means by which it is operated, and also showing a section of a power-wheel against which the stream of wateris to be directed.

Fig. 2 is a vertical section through the chamnozzle is fixed by an upright bracket d a guide sleeve D, in which is seated and adapted to slide back and forth the plug D, which lies and moves in thelineof the axis of said nozzle. The forward end or head of this plug is made conicalor tapering at d and corresponds to the in clination or taper of the interior of the tip a, so that when pressed forward it will completely close said tip. Beyond this conical portion 62' the head of the plug or valve extends, and said extension is best made in a series ofreduced diameters (represented by (Z and varying in number as may be desired. I have here shown, for example, three, joining one another by inclined shoulders, as shown.

The plug D, which formsthe regulator, is moved back and forthby any suitable means; but those which I deem the best and which I havehere shown are as follows: Within the casing or chamber B is a shaft E, suitably mounted therein and having one end extending outwardly through its side in a suitable stuffing-box e, whereby through a. crank 6 connected to its end the operating-rod or connection F may be attached. Within the casing or chamber B the shaft E has mounted upon it another crank-arm 6 extending down wardly within the casing and having attached said tip is opened to its fullest extent and the largest amount of water will pass through the nozzle. By moving theplug to points inter mediate of these limits the amount of water discharged is varied correspondingly. The movement of the plug within the nozzle is a free and easy one, because it moves as readily in the water as it would in the open air, as it is wholly immersed therein, and its movement being gentle the change from one volume and force of water to another-may be made gradually and without any shock.

With this regulator the stream at the outlet of the tip a emerges in a sinuous annular water-tube concentric with the head of the plug without losing anyof its impulsive power.

With this device shocks, chokings, and

windings are avoided. There is no Waste of water and the shutting oif or the opening of a gate is unnecessary.

Having thus described my invention, what I claim as new, and desire to secure by'Letters Patent is- V 1. A nozzle regulator consisting of a nozzle having a conical tip a plug mounted within the nozzle and slidable in the line of the axis thereof said plug having a head corresponding to and adapted -to fill, when projected, the conical exit of the nozzle or its tip, and having also an extension beyond said head, formed in portions of successively smaller diameters, whereby the issuing Water is caused to assume an annular form concentric with the end of the plug, and its volume and force may be varied.

2. A nozzle regulator consisting of a nozzle having a conical tip, a plug slidable in the axis of the nozzle, and having a conical head conforming to and adapted to close, when projected, the conical tip of the nozzle, and having also an extension beyond said head formed in portions of successively smaller diameters, said portions joining each other by inclined or beveled shoulders.

3. Anozzle regulator consisting of a nozzle having a conical tip, a plug lying and adapted to be moved in the line of the axis of the nozzle, and having a head with a forward extension formed in portions of successively smaller diameters, adapted to control the nozzle exit,

, and the means for operating said plug consisting of an oscillating shaft having a crank arm connected with said plug and a second crank arm and an operating rod connected with said second crank arm.

4.-. In combination with the nozzle having a conical tip, the water casing or chamber'and water connection, a regulator for said nozzle I consisting of a plug slidable in the line ofthe axis of said nozzle and having a head formed in portions of successively smaller diameters, adapted to control its exit, an oscillating shaft mounted within the casing or chamber and extending through a suitable stuffing-box to the outside, a crank arm onv said shaft within the chamber or casing and having a connecting rod attaching it to the plug, a crank arm on the outer end of said shaft and an operating rod connected with said crank arm.

5. In combination with the nozzle having a conical tip, the water chamber or casing and water connection, a guide sleeve in the line of the axis of said nozzle, and lying within it, a plug mounted and adapted to slide in said guide sleeve and having a conical forward end with an extension therefrom formed in portions of successively smaller diameters adapted to control the nozzle tip, the oscillating shaft mounted within the casing or chamber and extending through a suitable stuffing-box to the outside, a crank arm on said shaft Within the-chamber or casing and having a connecting rod attaching it to the plug, a crank arm on the outer end of said shaft, and an operating rod or connection connected with said crank arm.

, 6. The water nozzle, the chamber or casing, and the water connection as described, in com bination With a regulator for the nozzle con sisting of a sleeve within said nozzle and in the line of its axis, a plug or valve adapted to slide in said sleeve and having a forward end or head with a conical portion, and an extension formed with portions of successively smaller diameters, said head or end being adapted to control the exit of the nozzle tip, the oscillating shaft within the chamber or casing of the nozzle and extending through a suitable stuffing-box to the outside, a crank arm on said shaft within the chamber or casing and having a connecting rod attaching it to the plug or valve, a crank arm on the outer end of said shaft, and. an operating rod connected with said crank arm.

In Witness whereof I have hereunto set my hand. I
